To (all whom it vim-y concern:

lie itknown that l, 'ILLIANI'T. M. BRUN- XEMEPL, n citizen of the United States, residing at .iloninoutlu'in the county of \Varren and Slate of Illinois, lmve invent-ed certain new nnd useful lniprm'einents in Disk Cultivators, oi \Vllltll the following is a specification. 7

A lending object of. my present invention is to provide-disk cultivntors in which the disk gnngs are connected with n inn-in frame, comprising in its structure a rigid or nonllexible nxle, which main frame is mounted on wheels; until is pivoted to the rear end part of the tongue in such manner that said main frame andits SllllPOl'tlllgfiYl[0Ql5()l, as it inn) he termed, the truck" can be turned si(lewise,sltil'ted or deflected laterally in either direction from the path of movement or line of travel oi the cultivator by simpl forcing the forward end ol the main frame and the rear end of the tongue laterally in the direction desired, and in which the disk gangs nre eonuemed with the main frame in such ntnnner us to permit of the gmzgs being raised nnd lowered, while the connection at their front and reurends to the main lrnmeissuch that 'l1(? \'S\\'lll f laterally with the main frame orniovcin unison withall lateral movements ot the main frame, and such thattheir movements 'ln'ternlly are controlled b vthe lateral moven'ieut of the nminfrmnc and wheels or truck to erode plnnts or hills oi plant-s out ol'line in the row of plnnts,z1nd for other lllllPOfiOS; untl another nniin object of my invention to provide disk cultivutors in which the disk gangs are connected with a main frame supported on wheels, by menus whereby said gangs can be raised and lowered relatively to the main frame, and in which; the series of connected d inks of each gang are udjustnble zit ditierent angles horizontally and relatively to the line of travel of the cultivator, end at ditl'er'ent angles 'vcr-,

tic-ally nnd relatively to a line transversely ot' the eultivator,a-nd inivhieh the main frame is pivoted to the rear end part of the tongue in such manner that said frame and its supor line of travel of the cultivator, for the purpose of guiding the main frame on d wheels and thereby guiding the disk gangs to evade plants out of line in the row of plants, and for other purposes in the operation of the eultivnt or. 7 r

The foregoing stated leading objects and other objects of my invention are hereinafter 7 described, and the preferred novel means employed in carrying out; such object-s of the invention, the preferred organization of the parts, the preferred structural peculiarities of the different parts, and the new combinations of parts, are also hereinafter described, 6 5' and made the suhjeet-mntterof claims hereto appended.

\Vhat 1 herein term the main frame J, Fig. 1, consists principally of the axle and the U-sl1aped bar the cnrvedpart c of which is forward, and the; rear end parts (:Of which are fixed by clips e to thepart (r of the axle. A bar 0'' extending across the inain frame and fixed thereto a short distance forward of the. axle a bar c extending aeross'the main frame with ends c Fig. l, extending a short dis tance beyond each side therot', and fixed end of said frame and below it a bar c e):-

Lively to the other wheel, and the main frame swung laterally at its forward end on the bolt (1 as its center ol' motion in guiding the xnachine. as hereinafter more l'ully described. The friction between tho tongue and the transverse bar If is minimized by means of a roller (l beneath the bar/5, which isjournalml in and supported by bars ll" which are fixed to the bars (I' or roarcnil of tho tongue.

'l'he oporators scat l) is supported on the which pass tlli'niltlll oil her ol' a series ol'. holes (J lin each bar I! loriho purposeofadjusting the seat E forward or rearward to suit different operators. 'lho seat-bars e and seat may be turned upwan'dly andlorwardly on the bolts 0 as shown b i dotted lines at Fi 2 to turn it out of the way when desired.

The d isk gangs, as I have herein tcrined them, each consist of an ordinary disk gang G, formed of a series of disks {1, mounted, as may be preferred, to rotate on or with a diskgang axle g; which axle is carried by downhangers or pendants fl'Olll a connecting head or bar 'lhedisk gangs aroadjnstablycon nccted hereinafter described, one with each of the horizontal. ends 71 of a yoke or tieareh ll, the central part ll of which is of arched form to pass over plants of some height, does the arched axle A.

The draft rods or beams l. are each provided with an eye 1 at its t'orward end, which eyes are seated one on each outer end c of the bar c and are each adjustable laterally of the draftwod and lengthwise of the bar 0 and are fixed in position after such adjustments by means of a pin or split key i", which passes through a slot. in the eye 1 Fig. 1, and into either of a series of holes c in the bar 0, thus fixing each draft-rod 1 against 1n0veinent endlong of the rod 09, while allowing" it to partially rotate thereon to permit of its rear end rising and falling for purposes hereinafter described. The eye '4' is preferably hinged or pivoted at i to the draft-rod to facilitate adjusting it on the. bar c but this hinge is inoperative and the draft-rod practically a rigid rod in so far as lateral fiexure thereof is conccrnedwhen-the rear ends of said rods are held against relative lateral IIIOVGIlIGIltS, as hereinafter described.

The. rear end of each draft-rod I, as shown best at Figs. 6, 7, 8, 9, IO and ll, is fixed between a head below said rod and another head J above it, and is held principally by an eyebolt j, in the eye j of which the rod I is seated. The upper portion or body of the eyobolt j passes through-the head J upwardly close to the end h of the disk-gang yoke and through a block j which rests over and upon the end 7L ()1? the yoke ll, above which block j a nut j" on said cycholt is used to lit the (.lral't-rod I to the head .I and both to the end la oi thc yokc IL. The rear end of the draft- .rod 1 is"preferablyseated in agroovej in the place against angular movementron the eyej: The rear end ofthe drafta'od rests on ,a raised portion g of the licadig Figs. 10 and lit." on each side of which is a curved groove or-rocess g, in one orthe other'of which the oyo of the eyebolt I. is seated, as hereinafter described. At each end of the block is a recess 9 Fig-s1. 8 andlo; in which the head The yoke II on which the disk gangs aremounted has a journal parth" at each of its ends, which are seated each in a bearing Zin the distal end of a radiusbar L, the proximal end of which is in the form of 'a sleeve Z journaledon the end part (.6 of the axle A in such manner as to permit the radius-bar to oscillate on its bearing on. the axle, but to prevent it moving lengthwise of the axle, or, in other words, laterally of the cultivator. The shoulders its at each end of the yoke, abutting each against the adjacent radius-bar L, will prevent the yoke n'ioving endlong of itself, or, in other words, laterally oi." the cult i vatoxgand thus the radius-bars, while swinging on the axle A to permit olfraising and lowering the yoke It with its disk gangs, will in operation in the field retain or hold the yoke and the disk gangs from either angular or lateral ,movement with reference to the. axle A and wheclsll, and thus cause the disk gangs to swing or turn with all swinging movement's laterally of the main frame while held firmly at right angles with the axle and parallel'with the wheels.

The disk on s are raised and lowered each gang to a certain extent independently of the other gang, by a hand-lever M. Each hand-lever is fixed on or to the endof a short rock-shaftm, one of which rock-shafts is journaled'in suitable bearings m at each end of the part d of the axle A. Each rock-shaft m has a radius-arrn m projecting therefrom, with the distal end of which the upper end of a link m is pivotally connected, the lower end of which link passes loosely through. an eye h on the end of an cyebolt If which passes through and is fixed to the end it of thcyokell. Theprojeeting ends of apinm, which passes throughthe lower end of the link m, contact with the eye h when a lever M thrown forward for elevating the disk gang connected therewith above the ground, as shown bestat l igs. 2 and 3, and by the full lines at Fig. 5. When the hand-levers are swung-to the rear and there'lockcd, as here inaiter describedJo-r regulating the depth of plowing for operation in hard soil, the disk gangs will;be lowered into positions'for operations in such soil, as shown best at Fig. ,4, and by dotted lines at' Fig. 5, with the pin or forced out of contaetwith the eye h and the disk gangs forced and held downby a- -yielding spring-pressm'c force exerted by the springs mfl-w'hichare then each compr sedbetwecn ;ihe cye' 72$ and a stop-block m'lwhich is ad-.

- "justably mounted on the link or and held afd-er adjustmentby means of nsctscrcw m By ad ustments of the slop'block m" thetenogsion ol' thc spring in! can be adjusted to exert a greater or lrss spring-pressure on the disk gang for operating in'soils of dillferent degrees of hardncsspwhilc of not too greattension to prevent the gangs rising to pass I over obstacles which they cannot cut through. The hand-levers M are each provided with an ordinary spring-actuated dog. or catch 7rd, which is operated by athuinb-lever m to draw the dog out of engagement with either of the series of notches or depressions n in the curved rack-bar N, with which it has been engaged to lock the hand-levers, for plowin in hard soil, hereinbefore described. 13y engaging the links or eyes m each with the adjacent coacting thumb-lever on" the dogs m can be held out of engagement with the depressions inthe curved rack-bars X, whereby the disk gangs will be permitted, for use in ordinary mellow soil, to rise and fall to pass over obstructions and will not be held or forced down by the weight of the driver, the wheels, the main frame and the intermediate springs, as is the case when the hand-levers are locked to the rack-bar by the dogs in for operation of V the disk gangs in hard soil, as hereinloefore described.

A pivot-bolt Fig. 1, through the equalizer-bar 1, mid-length thereof, connects said bar with the central part of the forward end 0 of the U-shaped bar C. A pendant ltis pivotally mounted at its upper end on each end of the equalizer-bar 1, so that they can swing forwardly at their upper ends, as shown by dotted lines at Fig. The lower end of each pendantR is connected by a jointed link rod '2' with a lug l which re 'ects downwardl Y from the radius-bar L at the samcside of theto work, and asshown l )y dotted lines at Fig. 5,

will tend to draw the rear-ends of said radiusbars downwardly and thereby tend to force the disks into the ground. For-operation in hard ground the cleviscs r can be lowered in the series of holes r to sec-urea maximum effect of the draft in forcing the disks into the ground and the clevises can be adjustedin higher positions to secure a reduced forceaction of the draft in forcing the disks into the ground.

15y loosening the nuts j" the head.l and blocks can bc adjusted in different positions on the ends h of. the yokedL-and the disk gangs be thus readily adjusted at di'llcrent distances apart. \Vhcn such adjustments are made, the forwa id ends of the rods l should be correspoinlingly adjusted.

At Figs, 4: and 7 the dotted lines show different adjustments of the disk gangs, for the purpose of raising or liiwering either the outer or the inner ends of the disk gangs, as may be desired for diilercnt kinds of cultivation, in ditt'erent methods of planting, and in different soils. These adjustments last re- :terroi'l to are elt'eeted by means of raising the nut g on one of the bolts g and lowering the nut on the other holt, thus tilting or thruing the head 1 on the dralft-rod .l', as may he desired, at greater or less angles to a horizontal line and transversely of the cultivator. By turning the nuts g" to tighten them up closely after these adjustments are eti'eeted, the parts will be lined firmly and securely in place and to each other.

At Fig. 6 the dotted lines show one adjustment of a disk gang anguh'irly with referei'ice to thcline of t in vol of the cult ivat'or, This adjustment is cl'tected by loosening the nuts g" on the bolts 5 when the head and the disk gang may then be swung to any angle desired, by moving the bolts 1* to dit'lj'erent positions in the curved slots j. After such adjustments, by tightening up the nuts and drawing the parts gf" ot, the head tightly against the rear end of the dralt-rod l,.thc parts will he again secured tirmly in place and to each other. in making these zuljnstmcnts last rcferred to the eye j of. the eycholt j moves in the curved recess in which it is located. As shown in all of the drawings except lfig. it, the disk gangs are in positions to throw or move the soil toward each other, or toward the l'UV of plants being cultivated between the two disk gangs. The disk gangs may he reversed to throw thesoil in opposite directions from each other, or from the row of plants between them, by changing them and placin the righthan.d disk gang with its head 9" and lningers where the lct't-hand disk gang is located, and vice versa.

At Fig. .1 the disk gangs are shown as adjusted on the yoke ll to their locations nearest to each other, and as adjusted angularly to the line ol travel of. the cultivator in such positions that the l'orward parts of thc adjacent disks of the two gangs thereof 'will touch or approximately touch each other. With the disk gangs adjusted as last described, the cultivator-can he used [or fallow plowing, and where such plowing is done in stalk-holds the two middle disks will separate the stalks in a row thcreol' and t'oree them downwardly and outwardly to he severed into short lengths by the other disks.

lliy use oi? the means herein shown and dcsrriln-d l'or quickly and. easily moving the disk gangs laterally to evade plants out of line in the row cl? plants and t'or other purposes, and by the organization andcomliination olf disk gangs with such means and in such manner as to produce a thoroughly practical working cultivator ot' the disk gang type, a greatdcsideratum has been attained.

As is well known, disk gangs as ordinarily operated are ditlicult to move sidcwise readily amt quickly when in operation in the field. 'lh is di llioulty is overcome with my cultivator, as tlurdrivcr with his feet on the foot-plates S, which are lined, one to each end part of the axle A, can easily force either wheel l forwardly and thereby sway or turn the forward part of the main frame to one side, and cause the wheels to carry the main. frame and the disk gangs over to one side, not by forcing the disks laterally against the soil, but by changing their line of travel, comet dently with the wheels, so that they will olfer hutlittle resistance to such lateral movement. lly this means, cspeeiallylrv reason of simply turning the earrying-whecls out of the line of draft, while the disk gangs are held parallel and turned therewith the disk gangs are easily and quickly moved sidewise, even in veryhard soil, and in all ot. such operat ions the pathof the draft animals n ed not he (-ln'ingcd to guide the cultivator, and said animals can travel in lines parallijiling the row otf plants bein cultivated. After such deflection laterally'of the cultivator, it will he brought hack quickly into line by the draft acting on the forward end of the lengthy main frame, while the tongue is piv ted at its rear end to said main frame near the axle, on the cessation of pressure by the drivers foot, which return movement into line may he facilitated by slight pressure with his other foot on the other end of the axle.

An essential feature in causing the disk gangs to swing laterally with the main trame and wheels is the connection of the disk gangs with the main frame in such manner that they swing positively with .tho laterally swinging and laterally advancing movements of the main l'rame and wheels, or with the truck, and have not any, or aplnoximately not any, lateral movement except as they so move with the main frame and wheels; and this feature is accomplished or accompanied by means which, while preventing lateral movement of the disk gangs relatively to the main tiramc, will. permit of the disk gangs being ,raised and lowered for governing and controlling the depth ot cultivation, and for other purposes.

lly engaging the hook 'l, lrig. 3, which is hinged to the bar c of the main frame, with the eye lixod to the tongue, the pivotal eonnectionhet ween the main frame and tongue will cease and become rigid for use in moving the cultivator from place to place on its own wheels. \Vhen this hook is disengaged from the tongue, as shown best at Fig. i, then the pivotal connection between the main t'rame and tongue is operative.

The nature and advantages of the invention will be apparent and the principle or mode of operation will he understood from the foregoing description. it will be evident, however, that the in vcntion may be embodied in dilferent forms from what I have shown and described without departing materially from the general idea involved.

\Vhat I claim as new, and desire to secure by Letters Patent, is-
